1. Below are the balanced equations for the reactions in Parts 1–3. Review the results of your experiments and look closely over the mole ratios of the chemical reactions. Do your experiments reflect the stoichiometric, molar amounts indicated by the reactions? Discuss this using the evidence from your experiments.

Cu(NO3)2(aq) ARROW CU(OH2)(s)+2NaNO3(aq) Note: Cu(OH)2 is a blue precipitate.
FeSO4(aq)+2NaOH(aq) ARROW Fe(OH)2(s)+Na2SO4(aq) Note: Fe(OH)2 is a dark green precipitate.
Fe(NO3)3(aq)+3NaOH(aq) ARROW Fe(OH)3(s) + 3NaNO3 (aq) Note: Fe(OH)3 is a red-orange precipitate.
